Not a giant fan of windows behind the range, but it is what it is...so...most exhaust fan manufacturers and range manufacturers have determined the required air flow (cubic feet per minute - CFM) as well as the optimum distance from top of cooking surface to bottom of hood. Start by checking the specifications for CFM and distance from cooktop with the range manufacturer. Not sure of your location, but here in the States the IRC requires exhaust fans for kitchen, bath and laundry. Some areas, although they have adopted the Code, do not enforce it. But if broiling pork chops ever happens at your place...you sort of want it.

~$400 including expedited shipping. My GC just had his regular countertop guy do them, which wasn't great.... he had trouble making clean cuts. If I were going to do it again I would have pressed for someone with expertise to cut them. You can see in the image that the facing is not made of the stone peak, because too much was broken during the cutting to make the mitered edge. I'm a little bummed, but mostly pleased with the surface (which is the important part) thus far.

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.

The first couple of questions I'd want to know would be -- how much do you watch TV , and how often do you just sit chatting ? Also , what do the double lines between the 'drawing' and 'tv lounge' , and the 'ent lobby' and 'tv lounge' signify ? It doesn't appear to be a step , nor does it show as a fixed door ? Anyway , depending on priorities ( such as keeping an eye on kids while cooking ; or hiding the spouse when visitors arrive haha ) I would consider swapping the drawing and tv lounge , and put the TV on the solid wall in the 'front' room ( now called the TV lounge ) , that way you can spread 3 or 4 chairs and couches around the walls , similar to the existing plans , but to me the other bonus would be you can have suitable plants in pots in the 'open' area , and they'd be seen if you arrange the chairs in what is now the drawing room to suit -- basically , make that the area you sit and talking in , and make the plants part of the view and the conversation . There MAY even be the possibility of having a main TV in the 'new' front tv lounge , and still do a smaller 27 or 32 inch TV on a bracket in the 'old' tv lounge -- best of both worlds , and even the possibility of 2 seperate channels , without people heading to their bedrooms ( again , that depends on who is living there , and how 'dependent' they are on TV ) , but basically for a few hundred dollars ( if you have to buy another new TV ) you have another option ? Just a thought or two . . . . . . .
